TOUCH PANEL HAVING UNEVENLY DISTRIBUTED ELECTRIC FIELD LINES AND CONTROLLING METHOD THEREOF

摘要

A touch panel includes a screen, a substrate and a transmitting/receiving unit configured between the screen and the substrate, and having a first surface near the screen and a second surface near the substrate, wherein the size of the first surface is larger than the size of the second surface.

主权项

1. A touch panel, comprising a sensor including:
a transmitter having a first surface and a second surface; and a receiver having a third surface and a fourth surface, wherein when the sensor is operated, a plurality of electric field lines are generated from the transmitter to the receiver, the touch panel has a touch function side and the other side opposite to the touch function side, the first to the fourth surfaces respectively have a first to a fourth widths, the second width is smaller than the first width, the fourth width is smaller than the third width, the first surface and the third surface are closer to the touch function side than the other side, and the second surface and the fourth surface are closer to the other side than the touch function side such that the plurality of electric field lines distributed above a plane formed by an extension of the first surface and the third surface, and closer to the touch function side than the other side are denser than the plurality of electric field lines distributed below the plane, and closer to the other side than the touch function side.
